' s REVOLVING BRUSH.

Application filed February 23, 1922. Serial No. 538,591.

to revolving the form of brushes may be readily attached to or detached from a holding member, which is carried by a. revolving spindle or shaft, so that when any one of the units becomes worn, replacement may be easily made.

Another object is to provide a brush of this character in which the individual brush units may be replaced without the necessity of removing the entire device from the spindle, and which may hold brushes of different material.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification; it being understood that while the drawing shows a. practical form of the invention, the latter is not confined to strict conformity therewith, but may be changed or modified, so long as such changes or modifications mark no material departure from the salientfeatures of the invention as specifically Vpointed out in the appended claims.

In the drawing, in which similar reference characters designate corresponding parts throughout t-he several figures:

Figure 1 is a side elevation of the improved brush, partly broken away and showing one of the units in separated relation to the same.

Figure 2 is a transverse section through the same;

Figure 3 is a detail elevation of the unit holder or base member;

Figure 4 is an enlarged sectional View of the clip of the unit;

Figure 5 is a detail elevation of the clip, the brush being removed therefrom.

Referring particularly to Figures 1, 2 and 3 of the drawing, the invention comprises a circular unit holder or base member, in the form of a disc 1 formed of suitable metal, fibre, hard wood or other material strong enough to withstand the strain to which the same may be subjected in use` the said disc being of a diameterand thickness depending on the size of the brush as a whole. The disc 1 is provided with a central bore or aperture 2 which is adapted to receive the threaded end 3 of a machine spindle, or shaft 4' which may be part of any machine having the required speed, and said disc carries a plurality of clips or units, which may be readily attached to or detached from the same in a manner to be explained.

The disc 1 is provided with a circular series of round apertures 5 passing transversely therethrough and near the periphery of the same, the said apertures communieating with entrance openings or throats 6 in the form of relatively narrow slits eX- tending from t-he periphery of the disc to the apertures 5.

The brush units each comprises a metallic socket or receptacle 7 formed of thin metal into a rectangular box, considerably longer than wide. and having one end open for the reception of a plurality of strands 8 of wicking, cloth or fibres., or the same may consist of bristles, wires of varying gages. or any other desired material generally used for the different purposes to which such revolving brushes are put. The strands 8 are pressed into the box or receptacle, and the same may be crimped or pressed to hold the said strands rigidly and two opposite sides of the box are apertured as at 9, said apertures registering with a continuous passage 10 formed transversely through the strands for the reception of a split pin 11. While the strands illustrated are composed of wicking or similar woven material, the passageway for the split pin may be as readily formed through or between any of the other named materials which may be used to form the brush`Y polisher or burnisher or cleaner.

The boX 7 carrying the strands is adapted to be inserted between the spaced side walls 12 of a spring clip or holder 13 which is formed ot' fiat'spring metal of a width slightly larger than the width of the box, the said side walls being go-extensive with the length of the box, and havin inwardly directed end walls 14 adapted to abut against the closed end of the box, the end nos walls connecting with longitudinally eX- tending arms 15 lying flat against each other and forming a neck and terminating in an eyc or head 16 having an exterior diameter to snugly fit the apertures formed t in the disc 1, the arms fitting in and filling the throat 6, and the outer vfaces of the end walls 14, bearing against the outer periphery of` the disc, to prevent. the box carrying the brush elements 'from circumferential rocking movement during the rapid revolutions of the brush.

The outer ends of the side walls 12 of the clip are provided with apertures alining with the apertures in the box for the split pin 11, the ends of which may be suitably bent over to hold the strand carrying boX within the spring clip, as clearly shown.

When each of the apertures 5 is supplied with one of the brush units, elaml'iing plates .or discs 17 having central apertures 18 of a like diameter with the aperture 2 of the base member l, are adapted to be placed over the spindle and to be clamped to each side face of the said base member by suitable nuts 19, having threaded engagement with the threads of the spindle, whereby. the plates 17 may be tightly clamped against the sides of the member 1 so as to retain the brush units in place, the outer periphery of the clamping plates being located slightly within the outer ends of the several boxes 7.

From the foregoing it will be seen that a simple, cheaply manufactured and easily manipulated revolving brush has been provided` which is adapted to be made in varying sizes to suit the particular kind of work in hand. and that the same may be readily applied to the spindle or shaft for driving the same, and that by simply loosening one of the nuts 19, the adjacent clamping plate or disc 17 may be slid along the shaft or spindle to allow for the withdrawal of any one or all of the brush units when they become worn, and a new one or a set placed in position to be tightened therein by simply clamping the disc again in position by means of the nut.

What is claimed is 1. In a brush, the combination with a member having openings leading out to the periphery thereof, of holders fitted in said openings and removable therefrom, said holders'projecting from said member and bearing against the outer face thereof, brush material fitted within each holder. and means applied to opposite sides of said member to cover said openings and bear against the sides of said holders.

2. In a brush, the combination with a member, clips removably applied to the periphery thereof and projecting beyond said member, brush material fitted to each clip, and plates applied to the opposite sides of said member and of a greater diameter than the same, so as to bear against said member and also support the portions of the clips which project beyond said member.

3. In a brush, the combination with a member. clips removably applied to the periphery thereof and projecting beyond said member, sockets carrying brush material and fitted within said clips, and plates applied to the opposite sides of said member and of a greater diameter than the same, so as to bear against said member and also support the portions of the clips Which project beyond said member.

4. In a brush, the combination with a member having openings adjacent its periphery which lead out to the outer edge thereof, a series of clips adapted to said openings and filling the same and projecting beyond said member, each clip bearing at an intermediate point of its length against the outer edge of said member, brush material tted within and secured to each clip, and plates applied to the opposite sides of said member to cover said openings and also proj eeting beyond said member so as to bear against the opposite sides of said clips and support the latter.

5. In a brush, the combination with a holding member having a series of spaced openings near its outer edge, and slits leading from each opening to said edge, of clips having heads fitted in said openings, reduced necks filling said slits, and projectin side walls which bear against the outer e ge of said member, sockets carrying brush strands fitted between the side walls of said clips. means for holding the sockets within the clips, and clamping plates applied to the opposite sides of said member so as to cover said openings and slits and bear against the opposite sides of said clips.

6. In a brush, the combination with a disk-like member having a circular series of spaced round openings, with slits communicating with the openings and leading out to the periphery of said member, clips having a portion fitted in each opening and slit and projecting from said member and bearing against the periphery thereof, a box like socket carrying strands of brush mate rial and fitted within each clip, means for holding said sockets within said clips, and clamping plates applied to the opposite sides ot' said member to cover said openings and slits and bear against the opposite sides of said clips.

7. A revolving brush comprising a disclike member having a central aperture for mounting on a driving spindle, and a cir cular series of spaced round openings transversely through the disc adjacent to the periphery of the same. said openings comvmunicatingwith radial slits which extend to the periphery of the member, a clip for each opening formed of thin, flat metal provided with an eye adapted to lit in the opening und having` a reduced neck lot'ated 1n the radial slit and terminating in outwardhv extendingr spared prongs hearnig against the periphery ot' the dise and provided with apertures near their outer ends, a box-like brush holdingr socket Carrying strands and having transverse openings adapted to aline with the apertures in the prongs when the box is seated therein, a split pin adapted to pass through the Same as my own, I have hereto affixed my signal 20 ture.
